For years, I have dismissed Virtual Machine Hardware version as unimportant. In fact, in this very blog, I may have advocated for leaving VM Hardware Version set at 8, to maintain full compatibility with both the vSphere C# Client and the vSphere Web Client. Unfortunately, thanks to Spectre and Meltdown, things have changed. Updating your… Continue reading “Virtual Machine Hardware Version does make a difference”
Invalid snapshot configurations happen. Mostly, they occur because of problems with storage arrays during snapshot creation/consolidation, but they can also occur if certain process become interrupted (like replication) mid-snapshot. The more heavily you rely on snapshots, the more likely it is you will come across a problem with snapshots. Specifically if you use a product… Continue reading “Invalid Snapshot Configuration”
Many people are under the incorrect belief that it is hardware-level firmware updates from companies like HPE and Dell that will protect our Virtual Machines from Speculative Execution Vulnerabilities. This is NOT TRUE. As far as your VMs are concerned, the VM BIOS and Hypervisor are the hardware!
As we are all aware, recent updates to Shockwave Flash caused the vSphere Web Client to crash on most browser platforms. The interim solution was to install an outdated version of Shockwave Flash, just to access the Web Client. More recently, Adobe Shockwave Flash version 220.127.116.11 was pushed out in updates to Google Chrome (and… Continue reading “The VMware vSphere Web Client is fixed (sort of – until next time)”
Photon OS installs by default with DHCP enabled. This is perfect for building and distributing Photon OS OS as a Virtual Appliance, but for most practical applications, you’ll want to set a static IP address. Changing the IP of Photon OS involves a newer, albeit standardized procedure of editing files located in: /etc/systemd/network that will… Continue reading “Setting static IP for Photon OS”
For some users, whether you should or shouldn’t use SSH is a matter for debate. Rather than be hypocritical, I simply acknowledge that most admins will access Linux systems using SSH, and prefer to suggest that using strong passwords or passphrases and secure Management Networks is a more realistic approach to Linux administration.
VMware photon OS is described as “yum compatible.” Yum has been the package manager for all Fedora derivative distros like RHEL and CentOS. Photon OS actually uses Tiny DNF (TDNF), which appears to be a fork of the Fedora DNF package management system.
When I first started using VMware products, ESX Server ran on Red Hat, Virtual Center (vCenter) ran on Windows, there was no such thing as a “Virtual Appliance,” or at least the term had not yet been coined and Photon OS was a long way in the future!
Over the weekend Google pushed out an update to Flash (18.104.22.168) with an update to Chrome (61.0.3163.100) and now vSphere Web Client is broken once again!
VMware Workstation Pro 14 is a 64-bit Type 2 Hypervisor that is available for Linux and Windows. As a Type 2 Hypervisor, Workstation Pro runs as an application on top of a full Operating System like Windows 10 or Ubuntu Desktop and claims compute and hardware resources from the parent OS, then allocates those resources… Continue reading “Installing VMware Workstation Pro 14”
